Tagraíonn meaisínithe CNC don phróiseáil a eisíonn an córas rialaithe chun an uirlis a dhéanamh chun gluaiseachtaí éagsúla a chomhlíonadh a chomhlíonann na ceanglais, agus cruth agus méid an phíosa oibre a chur in iúl i bhfoirm uimhreacha agus litreacha. Tagraíonn sé go ginearálta don phróiseas meaisínithe páirteanna ar uirlisí meaisín CNC.
A CNC machine tool is a machine tool controlled by a computer. The computer used to control the machine tool, whether it is a dedicated computer or a general-purpose computer, is collectively referred to as a numerical control system. The movement and auxiliary actions of CNC machine tools are controlled by the commands issued by the CNC system. The instructions of the CNC system are compiled by the programmer according to the material of the workpiece, the processing requirements, the characteristics of the machine tool and the instruction format (NC language or symbols) specified by the system. The numerical control system sends running or termination information to the servo device and other functional components according to the program instructions to control various movements of the machine tool. When the machining program of the part ends, the machine will automatically stop. For any kind of CNC machine tool, if there is no program command input in its CNC system, the CNC machine tool cannot work. The controlled actions of the machine tool roughly include the start and stop of the machine tool; the start and stop of the spindle, the change of the rotation direction and speed; the direction, speed and mode of the feed movement; the selection of the tool, the compensation of the length and radius; the replacement of the tool, the cooling Opening and closing of liquid.
